We divide 21259092 by 311
The aim is to understand the frequency of 311 in 21259092.

Let's proceed to step 1:
311 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 311

Moving on to step 2:
311 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 311

Let's proceed to step 3:
The number 311 fits into 212 0 times, leaving a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 212, we end up with 212.
Fetch the next digit (5) from the dividend, attach it to 212 and continue: 2125 / 311

Let's proceed to step 4:
If we divide 2125 by 311, we get 6 and a remainder of 259.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 1866 from 2125 and we're left with 259.
Include the next digit (9) from the dividend after 259, then repeat: 2599 / 311

Going ahead to step 5:
When dividing 2599 by 311, we get 8 with a remainder of 111.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we take 2488 away from 2599, we end up with 111.
Grab the next digit (0) from the dividend, add it to 111, then carry on: 1110 / 311

Going ahead to step 6:
The number 311 fits into 1110 3 times, leaving a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 683.0
If we take 933 away from 1110, we end up with 177.
Bring next digit (9) of the dividend behind the 177 and repeat the process: 1779 / 311

Step 7:
If we divide 1779 by 311, we get 5 and a remainder of 224.
Use 5 as the next digit of our solution. 
Result so far: 6835.0
Subtracting 1555 from 1779 leaves us with 224.
Bring next digit (2) of the dividend behind the 224 and repeat the process: 2242 / 311

Moving on to step 8:
2242 divided by 311 is 7 with a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 68357.0
Deduct 2177 from 2242 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
311 goes into 650 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 68357.2
Subtract 622 from 650 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
311 goes into 280 0 times with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 68357.2
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
When dividing 2800 by 311, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 68357.209
The remainder is 1 after subtracting 2799 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
10 divided by 311 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 68357.209
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
The number 311 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 68357.209
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 68357.209 with a remaining 0.0001.
